Predicted to enable hydrolase activity, acting on acid anhydrides, in phosphorus-containing anhydrides; metal ion binding activity; and phosphodiesterase decapping endonuclease activity. Predicted to be involved in several processes, including RNA decapping; circadian regulation of gene expression; and nucleobase-containing compound catabolic process. Predicted to be located in cytoplasm and nucleus. Predicted to be active in peroxisome. Orthologous to human NUDT12 (nudix hydrolase 12). [provided by Alliance of Genome Resources, Apr 2022]
